Our Sub Fleet Is practically DeCommissioned.
This Poster States We Have 71 Total Subs in service.

Two thoughts:
1) referring to above thoughts ... in 'The Hunt for Red October', the saying was, when they wanted to be stealthy, they "made like a hole in the water"

2) The Russian 'Kilo' is next to undetectable to our SOSUS network; The Red October was next to undetectable to our SOSUS network. Have the references to "Red October" been about this sub, all along?

@Rudis I certainly can't argue that Obama virtually decimated our military, both in terms of hardware and manpower. But I'll take quality over quantity every time. LA and Ohio class subs from an 90s ASW perspective, eere tough acts to follow. The Virginia class has some "enhancements" over LA boats that allow it to perform multiple missions that even producers of tech manuals go through BI's that Kavenaugh would most likely fail. The US learned a hard lesson when Toshiba sold us out to the Soviet Union. And I have no doubt Columbias will have huge improvements over Ohios.

And @Hickory SOSUS is so yesterday. It's like comparing LORAN to GPS. In the meantime, here's a short vid for you. Trust me, flying out of Thule Greenland, both myself and the mission commander learned some hard lessons while looking for one of two Typhoons ever produced. One of the lesser lessons for him was not to take flash photos while I had my hands in live electronics.https://youtu.be/DaHjPFn9ULM

Newer Kilo class? I'm familiar with the Kilo's that have been around for decades. They were very much a part of our recco training/testing in the VP community.

But in either "Hunt For the Red October" or "Red Storm Rising", there was a line in the book about detecting the big Ohio class boomers. "When you find a spot totally devoid of any sound (environmental or mechanical), you've found the sub."

Yeah OK. @1.23 mark, see that big white circle? Back in the day, that was the "beacon in the night" tell that you were looking at a Kilo.

Kilos were upgraded with a rubberized outer coating and maybe quieter engines? But, still the old Kilo class design I think.

Yeah, the Kilos have been around for decades and upgraded. To the point that the US P-8 Poseiden no longer has a Magnetic Anomaly Detection system. Other countries that bought the P-8 (India as one) requested theirs have the MAD system installed.

And I posted a quick vid on the Typhoon class boats just a few replies up.
EDIT: And "quiet" is a relative term. Ain't no diesel boat quiet enough to evade detection. Now the screws (props) are a different story. Cavitation is like an echo in the Grand Canyon.

‘This Won’t Be Subtle’: SpaceX West Coast Launch to Create Large Sonic Boom

Southern California residents are being warned to expect a large sonic boom Sunday evening as SpaceX launches a Falcon 9 rocket from Vandenberg Air Force Base, then attempts its first-ever landing on the West Coast, according to the company and military officials.

The launch is scheduled for shortly after 7:20 p.m., Vandenberg Air Force base officials said in an advisory. The rocket will carry the Argentinian SOACOM 1A radar mapping satellite.

Those near the base, which is near Lompoc, may be able to see quite a show as the first stage of the Falcon 9 rocket burns its rocket engines to come to a gentle landing back at the air force base, officials said.

As for Props..
It's really weird, I've seen photos of modern boats, both US and Russian, with their props exposed. They are generally covered with a tarp in order to avoid satellite pix. It's got to be some kind of spoof on the intel agencies? Why else would they both do that?
